GEORGE E. LAWRENCE, OF MIDDLE-TOWN, NEW YORK.

TRANSOM-OPERATOR.

Application filed September 24, 1907.

T 0 all whom it may concern:

Be it known that I, Gnonen H. LAWRENCE, citizen of the United States, residing at Middletown, in the county of Orange and State of New York, have invented certain new and useful Improvements in T ransom-Operators, ofwhich the following is a specification.

The present invention is designed to provide novel mountings for the sash arranged along the sides ofthe elevated portion of passenger coaches, as also to supply unique actuating means for simultaneously opening or closing the said sashes, said actuating means being adapted to be controlled so as to operate the sashes upon one side or the other to the exclusion of the sashes upon the opposite side as well as admitting of connecting all, or any selected sashes in series for Sin1ultaneous operation.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

\Vhile the invention may be adapted to different forms and conditions by changes in the structure and minor details without'departing from the spiritor essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a horizontal section of the roof portion of a car equipped with sash operating mechanism embodying the invention, the sashes being open. -Fig. 2 is a View similar to Fig. 1 showing the relation of the parts when the sashes are closed. Fig. 3 is a transverse section of the upper portion of the car on the line 00-51: of Fig. 1. Fig. at is a transverse section ofthe upper portion of the car on the line y-y of Fig. 2.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The present invention provides novel and automatic means for operating the sashes along the sides of the raised portion of passenger cars, and which sashes are usually 0perated by hand, thereby requiring special attention and consuming time in a tram of any length.

In accordance with this invention the sashes 1 are mounted so as to swing inward and downward at their upper edges. The

Specification of Letters Patent.

lower edges of the sashes are :rabbeted'to form shoulders 2 and a portion 3, which latter is made rounding; The shoulder 2 rests upon the lower side of the frame and supports the-sash from below when closed. Curved irons at are secured to opposite sides of the frames and are formed at their upper ends with inner projections 5 which engage with outer projections 6 of the sashes and limit the inward movement thereof, as shown most clearly in Fig. 3. Iron straps 7 are secured to the side or end bars of the sashes and their lower ends are bent outward to form the projections 6. Headed fastenings 8 serve to secure the straps 7 to the sashes andare also utilized to secure guards 9, which are fitted to opposite ends of the sashes so as to close the spaces betweenthe ends of the sashes and the ends of the frames, thereby preventing cinders or other particles from entering the car. The guards 9 taper in their length and increase in width from bottom to top and have inner flanges 10 at their attaching edges to receive the headed fastenings S, and which flanges are confined between the head of the fastening Sand the-strap iron 7, the latter serving to prevent the attaching edges of the guards from inarring the sash frames. To prevent noise when closing the sashes, as well as to relieve jar and insure a close joint, a weather strip llis secured to the upper portion of the sash frame for the latter to close against.

A rod or bar12 is fitted to the upper bar of'each sash in a manner to admit of its ready removal so thatthe sashes may be taken from their frames when required for any purpose. A sleeve or runner 13 is mounted upon each rod or bar 12 and is connected by means of links 14 and 15 to, re-

or bar 16, the latter being mounted for longitudinal movement. The end of the link let pivoted to the frame is fixed, whereas the opposite end is free to move so as to effect opening and closing of the sash. Each sash is provided with a pair of links 15 which embrace opposite sides of the sleeve 13 and a corresponding sleeve or fitting 17 adjustably secured to the operating rod or bar 16. As the rod or bar 16 is moved longitudinally to spread the outer ends of the cooperating links 1% and 15, the sleeve 13 is drawn outward towards the operating rod or bar 16 and efi'ects a closing of the sash, the sleeve 13 sliding upon the rod or bar 12.

- 29 connects one end of the motor cylinder 18 When the links 1 1 and 15 assume the position shown in Fig. 2, the sash is closed and upon moving the rod or bar 16 in the opposite direction to bring the sleeve or fitting 17 towards the fixed pivot end of the link 1 1, the sleeve 13 is moved inward and effects an opening of the sash, the latter being at the limit of its inward movement when the links 1% and 15 assume the position shown in Fig. 1. It is to be understood that the operating rod or bar 16 is connected in the manner substantially as shown and described with each of the ventilating sashes of a car so as to effect simultaneousmovement thereof. The sashes upon one side of the raised portion in the roof of a car are connected in one series and the sashes upon the opposite side of said raised portion are connected in a second series, each rod or bar 16 having connection with independent operating means.

At one end of the car or at any convenient point thereof is located the means for operating the rod or bar 16, said actuating means consisting of a motor cylinder 18, piston 19 arranged to operate therein, connecting means between the piston rod 20 and the operating rod or bar 16, and a valve 21 for controlling the fluid medium in its admis sion to and its discharge from opposite ends of the motor cylinder. A bracket arm 22 is secured at one end to the piston rod 20 and at its opposite end to a rod 23, which latter has a curved end 24- terminating in an eye through which the end of the operating rod or bar 16 passes, and which eye is confined between a pair of set nuts 25 mounted upon the threaded end of the rod or bar 16, there by admitting of adjusting the point of contact between the parts 24: and 16. A contractile spring 26 connects the bracket arm 22 with a post 27 secured to a convenient portion of the car, and said spring normally exerts a pulling force upon the bracket arm 22 so as to hold the sashes closed. The tension of the spring 26 may be varied by means of a threaded stem and set nut 28. A pipe with the valve 21 and a second pipe 30 con nects the opposite end of the motor cylinder with the valve 21. It is to be understood that the pipe 29 has connection with corre- I sponding ends of the motor cylinders provided for operating the sashes upon opposite sides of a car and that said pipe may consist of a main and branch pipes. The pipe 30 likewise has connection with a pair of motor cylinders and may consist of a main and branch pipes. To admit of throwing one of the motor cylinders out of action when it is required to operate only one set of sashes, a cut ofi valve 31 is provided in the length of a branch of the pipe 30. This prevents the admission of air into the inner end of the cylinder connected with the sashes to remain closed when operating the valve 21 to admit air into the opposite motor cylinder for opening the other set of ventilating sashes. The valve 21 has an exhaust 32 and an inlet 33, the latter being screened to prevent the entrance of foreign matter into the valve and obstructing the passages thereof.

Having thus described the invention, what is claimed as new is:

1. In combination with a swinging sash and a rod mounted to move longitudinally parallel with the axis of the sash and at a ri ht angle to the plane of movement of said sash, a link having pivotal connection at one end with the frame and having both pivotal and sliding connection at its opposite end with the sash, and a second link connecting said operating rod with the end of the first mentioned link having connection with the sash.

2. In combination, a swinging sash, a rod movable longitudinally parallel with the axis of the sash, a runner slidable upon the sash parallel with the axis thereof, a link having pivotal connection at one end with the frame and pivoted at its opposite end to the said runner, and a second link conneot ing the operating rod with the said runner.

3. In combination, a sash mounted to open and close by a swinging movement, a slide mounted upon the sash, a link oonnecting said slide with the frame in which the sash is mounted, a slidably mounted operating rod or bar, a fittinghaving adjustable connection with said operating rod or bar, and a link connection between said fitting and the aforementioned slide.

In testimony whereof I aflix my signature in presence of two witnesses.
